“Pengowan’s report states quite definitely that it is suicide,” he said as he replaced it. “In the face of that, do you think—”

“I think my brother has been murdered,” she said in a decided voice.

“This is a very grave statement to make, Mrs. Pendleton. Have you anything to support it? Anything which has not been brought to light, I mean?”

Mrs. Pendleton proceeded to give her reasons. She had thought over what she was going to say as she came along, and she spoke with growing conviction, intensified by the sight of the earnest attentive face before her. The incident of the person she had detected looking through the door took on a new significance as she related it. By her constant association of the eyes with the disliked face of her brother’s servant, she had unconsciously reached the conclusion that she had all along recognized the eavesdropper as Thalassa.

“You say your brother was talking about some family matters at the time?” asked Inspector Dawfield, as she related that part of her story.

“Yes,” responded Mrs. Pendleton. She had repressed all mention of her brother’s announcement of his daughter’s illegitimacy, but afterwards she tried to persuade herself that it slipped her memory at the time.

“It’s common enough for servants to listen at doors,” remarked Inspector Dawfield. “In this case it may seem to have a sinister interpretation because of what happened afterwards. How long has this man been in your brother’s employ?”

“A number of years, I believe,” replied Mrs. Pendleton. “But he has a wicked face,” she added hastily, as though that fact cancelled a record of lengthy service. “I took a dislike to him as soon as I saw him.”

Inspector Dawfield veiled a slight smile with a sheet of foolscap. “Have you any other reason for suspecting him?”

“Oh, I wouldn’t like to say that I suspect Thalassa, or anybody else.” Mrs. Pendleton was prompt with this assurance. “But there are certain things which seem to me to need further investigation. There’s the question of the door being locked on the inside. It seems to me that the door might have been locked on the outside, and the key dropped in there afterwards. The door had to be smashed before we could get in, and the key wasn’t in the door then, you know.”
